IMPROVEMENT IN GRAIN CLEANER AND sEPARAT-oa.

' Specification forming part or Letters Patent No. 40,942, dated December 15, 1863 antedatea December 12, 1863.

To all whom it may concern:

Be it known that I, J. W. PATTERSON, of Monticello, in the county of Wright and State of Minnesota, have invented a new and'lrnproved Grain Cleaning and Separating'Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the acco1n-,

panying drawings, makinga part of this specification, in which- Figure 1 is a vertical section of my invention, taken in the line a: as, Fig. 2; Fig. 2, a

vertical section of the same, taken in the; line :11 9 Fig. 1; Fig. 3, a section of a portion of the same, taken in the'line z 2, Fig. 2; Fig.4, a detached plan or top view of the beater pertaining to the same Fig. 5, a plan or top View of a portion of Fig. 3.

Similar letters of reference indicate corre sponding parts in the several figures.

The object of this invention is to obtain a machine of simple construction which-will effectually separate cats from wheat, and also separate smut and all other impurities from the grain.

To enable those skilled in the art to fully understand and construct my invention, 1

will proceed to describe it.

A represents a framing, which maybe constructed in any proper manner to support the working parts of the machine, and Bis a vertical shaft, which is placed centrally in the framing A, and has a blast-fan, 0, on its lower part, said't'an being inclosed within acylin- On the shaft-B, some, distance above the fan (J, there is placed abeater,"G,lwhich is formed of a series of radial arms d, attached to a hub, e, the latter being keyed on the shaft B. The outer parts of the arms at are connected by oblique'bars c, as shown clearly in 4, and to these oblique bars e beatersf are attached, said heaters having a corrugated outer surface, and their upper parts be;

ing vertical and their lower parts a little in-, clining outward, as shown clearlyin Fig. 4 The corrugations of the beaters f are in a vertical position, and the inner ends of the beatment the boaters f may be adjusted to a certain extent farther inward or outward on the bars 6!, as several holes maybe made in each beater f for the screws or pins 'h to passthrough, as will be fullyunderstood by referring to Fig. 4. This beater G is encompassed by a perforated cylinder, H, which rest-sorta circular base-plate, I, the latter having a circular hole, 1;, at its center and an opening,

near its edge. I

J is an inclined spout On the upper end of'the perforated cylinder H there is screwed a horizontal plate, K, to which a vertical tube, L, is attached centrally. The lower part. of this'tube is perfoated, and it has a bearing, k, fitted in it for the upper part of the shaft B. On the upper end of the shaft B there is fitted two spiral wings or arms, l l, the use of which will be presently explained. The perforated cylinder H is inelosed by side plates, an mfand the vertical parts of the blast-spout E, and the lower part of this inclosure communicates with the fan-case D by means of passages on, bot-hot which areshown in Fig. 2;

latter, P ,being connected to the front'or lower end of the shoe. (See Fig. 2.) the levers P P are designated by 0 0.

The-fulcra of in giving theshake motion. The shoe Neontainsfour screens, Q Q, Q Q', and each screen vis provided with-a lateral discharge-spout, p at i'tslower .or discharge end, and has also an inclined plate or. chute, q, below it. The screen Q has its discharge end at the back part of the shoe N. The arrangement of the screen is fully shown in Fig. 3. To the upper part of the shoe N there are attached two side which leads from the opening 1;, as shown in Fig. 1.

AL spring, 0, acts against the lever P and assists tation breaking the grain, which is discharged through-the openconnected by bars, 4* r, the ends of which are S is designed a cross-bar, S. This cross-bar to be under the lower end of the hopper, and

the vertical tube L,the screen s in the shoe eifectually separating oats't'rom the wheat as Well as straw and other foreign substances. The wheat is discharged from. the lower spout, p, into the tube L. The rotating arms l l scatter the grain and cause it to be Well distributed within the cylinder H, the beater G by its'rolsmut and scouring the ing j into the spout E, where it is subjected to a blast generated by the fan 0, the direction of which is indicated by the red arrows in Fig. 1. The light-impurities are all drawn up by the suction through the spoutE and into the fan-case I), from which they are expelled by the fan. Ohessandsubstances of value 001- lcct in the lower part of the spout below the plate I), and are discharged from the spout through the flap F. By adjusting the plates f farther in or out on the bars 0 their action on the grain may be modified to a certain extent. periora'tions of the cylinder H is drawn down through the passages n a into the'fan-case D, andexpellcd therefrom with the dust that is received into the fan-case from the'spout E. Over the beater Gr there is placed a perforated plate, 1%, to prevent the admission of grain within the beater. The passage of the generator by the'revolution of the beater G is indicated by the red arrows in Fig. 1. The bar 8 vibrates, ot'course, with the shoe N, and, as before stated, effectually prevents the lower-end of the hopper becoming choked or clogged.

Having thus described my invention, what I elaiinas new, and desire to secure by Letters Patent, is

1. The revolving spiral arms l 1, attached to the shaft B, where said arms are used in connection with the beater G and perforated cylinder H, as and for the purpose specified.

2. The bar S, attached to the upper part of the shoe N to prevent the choking or clogging of the hopper, as specified.
